Said rendering available some of the advantages and pick-up comprises a suitable frame 23 having economies of the combination harvester method fingers 2| secured to its lower end by the memto crops grown under such climatic conditions, bers 25, which are attached to braces 26 (Fig. 5),

The pick-up is pick-up. provided with suitable depth gaging means such 55 arrows in Fig. 1; belt 45 preferably running around a countershai't 41. The canvas driveroller ll may be driven from any convenient source on the thresher, as the sprocket ,con-

gear 52. which drives a companion spur-gear on the end of countershaft 41. and on the op site end of said countershaft is a sprocket 54 about which runs a sprocket chain 5!. and connects the same to roller sprocket 32.

ing engaging the grain will travel same direction, as indicated by the arrows in Fig. 1.

To the axle I2 I rotatably mount a pair of carrying arms 68, which may be secured thereto sleeve 6| mounted on shank 65, pivotally connected at I to each side of the pickup, and connected by a brace arm 60 is in efl'ect a bifurcated to support the pick-up from the thresher, the pick-up, being plvotally supported thereby is free to By this means the elevator portion of the pick-up is not only permitted to move upwardly and downwardters.

As hereinbei'ore indicated. the weight of the thresher is sustained by the rearwardly extending arms I, so that the pick-up is counterbalroller sprocket 56 and drive- C", so that said arm is hingedly connected to the axle I! by the coupling ii the pick-up may be swung away from the thresher, as indicated in Fig. 6, ior convenin making adjustments or repairs.

In the circumstances hereinbei'ore described. where the grain is tion harvester-thresher in place of the harvester or header element thereof, so

tieed with a combination harvester-thresher.

In operation, the combination machine is so guided that the pick-up will move into the windadvances, the fingers 24 pick up the loose grainladen straws,

which move along over the group urged toward the elevator portion of the pick-up by the revolving fingers 38 to the canvas belt 45 receding within the drum wn in Fig. 5, which drum, as

indicated by the arrow rotates in a direction opposite to that of the depth gage wheels 39. The finger members 25 are preferably made of spring material so that when fingers 24 strike obstructions they will yield and pass thereover. During such movement of the straw the elevator belts ll, 45, coopelji-te to convey the material upwardly and deliver the same from its mouth 11 into the sloping hopper ID, from which it moves by gravity into the feeder-housing 6 of the thresher to be threshed and separated. While thus traveling the gage wheels 3! follow the ground inequalities and thus maintain the fingers 24 in proper relation to the soil, and, as the pick-up is pivotally mounted upon its supporting arm, which latter is linked to the thresher as stated, it is enabled to follow the movement of the thresher without strain, and by which means in connection with the variable coupling between said arm and the thresher I provide stable but yielding connections between the thresher and pick-up elements of the combination machine.

I claim as my invention:

1. In a windrow pick-up, means at its forward side for removing cut grain from the soil, a revolving drum positioned rearwardly of and cooperating with said means, fingers in the drum adapted to project and recede in relation thereto for propelling the cut grain, and means for receiving said grain from.the fingers and discharging the same from the pick-up.
